Colonic ganglioneuroma. Report of a case in a patient with neurofibromatosis, multiple colonic adenomas and adenocarcinoma.

A 73 year old woman with cutaneous neurofibromatosis developed colonic carcinoma. The resected colon also contained multiple tubular adenomas and a polypoid ganglioneuroma. Multiple neurofibromas were seen during the operation over the serosal surface of the small intestine. Other cases of colonic ganglioneuromas and of combined neurogenic and epithelial colonic tumours are reviewed.
